David has been working at UM-CIGLR since 2013. His current research focuses on how invasive species have affected diet, growth, survival and recruitment of larval fish, through changes in spatial organization of the lower food web in Lake Michigan and Lake Huron. When David isn’t in the lab processing samples, he is out in the field deploying and analyzing samples using a suite of instruments (Niskin bottles, CTD, Plankton Survey System with a Laser Optical Plankton Counter, zooplankton, mysis and larval fish tows, MOCNESS and fisheries hydroacoustics software). His expertise includes assembly, maintenance and operation of the MOCNESS (Multiple Opening and Closing Net Environmental Sensing System). David also analyzes the data using several packages including Bioenergetics, Echoview and Biosonics software. Each year he also mentors CIGLR summer fellows, graduate students and student volunteers. In the past, David contributed to research involving benthic ecology and microplastics.
